On Dec. 1, 1964, the club known as the Colt .45s was officially reborn as the Houston Astros.

As the club changed its name, Astros President Roy "The Judge" Hofheinz was excited about the new image. "The name and insignia will help dispel the image Texas as a land of cowboys," Hofheinz said. "It behooves every citizen in this area to call attention to the 20th century aspects of Texas and Houston."

The Astros have had a lot of different looks through the years, ranging from their 60's look to the crazy rainbow uniforms of the '80s. Here's a look at the evolution of Astros' uniforms through the years.

1965-70When the team moved into the Astrodome in 1965 they changed their name to the "Astros" to reflect the city's new image as a leader in space exploration. Their new uniform featured the name "Astros" with a shooting star above the logo. The colors were orange and navy.

In their first ever regular season game, the Houston Colt .45s defeated the Chicago Cubs, 11-2.

The Astros came out with a radical new uniform, later referred to as the "rainbow" jerseys. The uniform featured a block of orange stripes across the entire chest area, with "Astros" across the top.

1987-93What started out as the road uniform during the rainbow uniform years became the new Astros uniform. The uniform featured a white jersey with rainbow stripes down the shoulders and "Astros" across the chest. The "rainbow shoulders" uniform is the longest running uniform for the Astros.
